You can implement the `Signer` trait to extend functionality to other signers
|
||
|
|
such as Hardware Security Modules, KMS etc.
|
||
|
|
|
||
|
|
The exposed interfaces return a recoverable signature. In order to convert the
|
||
|
|
signature and the [`TransactionRequest`] to a [`Transaction`], look at the
|
||
|
|
signing middleware.
|
||
|
|
|
||
|
|
Supported signers:
|
||
|
|
|
||
|
|
- [Private key](./type.LocalWallet.html)
|
||
|
|
- [Ledger](./struct.Ledger.html)
|
||
|
|
- [YubiHSM2](./struct.Yubi.html)
|
||
|
|
- [AWS KMS](./struct.AwsSigner.html)
|
||
|
|

|
